当前,美军正大力研制战斗工程与架桥设备。一般说来,该项研制工作投资较低。桥梁的发展要此通过桥梁的主要武器的发展落后约10—20年。对新型桥要求架桥、通过、拆桥时间短;要用机械式竖桥代替人力竖桥;要在后方装备好后再架设,以便减少暴露时间;桥梁易于重新收回,收回后可继续架设。另外,新型桥的研制,还使用国际通用原则,即在某一国家研制的新型架桥设备,可在西方国家(如美、英、西德,以色列等)通用。新型桥,将对桥梁跨度和承载力进行折衷考虑并降低桥梁部件的重量。 At present, the U.S. military is vigorously developing combat engineering and bridging equipment. In general, the research and development investment is low. The development of the bridge is to be lagged by about 10-20 years for the development of the main arms through the bridge. The new bridge requires bridging, passing, dismantling the bridge a short time; to use mechanical vertical bridge instead of the human vertical bridge; to be equipped in the rear and then erection, in order to reduce exposure time; bridge easy to recover, the recovery can continue to set up. In addition, the new bridge development, but also the use of international common principles that developed in a new type of bridge equipment, can be common in Western countries (such as the United States, Britain, West Germany, Israel, etc.). The new bridge will compromise bridge span and bearing capacity and reduce the weight of the bridge components.
